My AC Guy Says I Have to Get a Heat Pump Because the Law Changed

No.

If you currently have a straight-cool air conditioner with electric heat, you are not automatically required to replace it with a heat pump because “the law changed.”

There have absolutely been HVAC regulation changes.

The big recent change involves the refrigerants used in new residential HVAC systems. Federal rules restrict higher-GWP refrigerants in new systems, which is why you’re now seeing equipment using refrigerants such as R-454B and R-32.

But those federal rules specifically regulate residential air-conditioning AND heat-pump systems.

They did not eliminate straight-cool air conditioners.

Can You Still Install Straight Cool in Florida?

Yes, provided the equipment and installation meet the applicable efficiency, refrigerant, building-code and manufacturer requirements.

Florida’s HVAC replacement requirements include things such as proper equipment sizing. They don’t create a blanket rule saying an existing straight-cool system must be converted to a heat pump.

So you can still have:

Straight-cool AC + electric heat

or

Heat pump + backup electric heat.

Which One Should You Get?

That’s a completely different question.

A heat pump can provide heating much more efficiently than relying solely on electric resistance heat, so there are legitimate reasons we may recommend one.

But:

“We recommend a heat pump.”

is very different from:

“The law says you have to buy a heat pump.”

The Klein Answer

If someone tells you a new law means you have to convert your straight-cool AC to a heat pump, ask:

“Which law?”

There have been real HVAC regulation changes.

A Florida mandate requiring every straight-cool replacement to become a heat pump isn’t one of them.

Pick the system that makes sense for your house.

We don’t need to invent a law to make the decision for you.
